BETTER LUCK NEXT TIME

Even I wouldn't tell

atleast start

I would tell Atmost done at your side first and then come up with exact problem code where you have stuck.

The Best way to predict your future is to create it - Every great individual common man

Sorry, we do not have a homework forum. Try and do some of the problems yourself. If you are really stuck try our Java In General (Beginners) forum, presenting an exact description of the difficulty you are having. I will not move this post because I will get beaten up by the JIG moderators.
